Open questions on methane hydrate nucleation [PDF]
Communications Chemistry, 2021 The commercial use of natural methane hydrate is hampered by several open questions that remain regarding hydrate formation. Here the authors comment on past interpretations and aim to provide a roadmap for developing a predictive theory of methane hydrate nucleation.

Intensifying the process of methane gas hydrates crystallization in the presence of surface-activated substances [PDF]
E3S Web of Conferences, 2021 The crystallization process of gas hydrates during their formation in the presence of surface-active substances (SAS) is studied. The research is conducted in two directions – theoretical and experimental. Experimental data on the crystallization rate of

Characteristics and varieties of gases enclathrated in natural gas hydrates retrieved at Lake Baikal
Scientific Reports, 2023 Molecular and stable isotope compositions of hydrate-bound gases collected from 59 hydrate-bearing sites between 2005 to 2019 in the southern and central sub-basins of Lake Baikal are reported. The δ2H of the hydrate-bound methane is distributed between −

ANALYTICAL REVIEW OF TECHNOLOGIES OF THE INDUSTRIAL DEVELOPMENT OF AQUATIC METHANOHYDRATES
Геологія і корисні копалини Світового океану, 2022 Methane hydrates are one of the most powerful reserves of unconventional sources of hydrocarbons. This is clearly evidenced by the forecast estimates of world volumes of methane in the form of gas hydrates, which many times exceed the total resources of ...

Density functional theory studies of hydrogen bonding vibrations in sI gas hydrates
New Journal of Physics, 2020 To analyze the vibrational modes of water and methane in structure I gas hydrates, we constructed a 178-atom supercell with two small cages of type 5 ^12 and six large cages of type 5 ^12 6 ^2 . We applied the density functional theory method to simulate
